Application filed May 24, 1922, Serial This invention relates to loose leaf bind ors employed for holding sheets or leaves temporarily in book form.

One'of provide a the leaves or sheets so asto permitnianipula tion, removal and replacement of the same.

Another object of this invention is to provide a loose leaf binder which is arranged to selectivelyhold the sheets either so as to permit them to'be turned from one back to another, or to hold them on one back of the binder. a i

I Another object of this invention is to provide a loose leaf binder which is simple in construction, effective in action and cheap to inanuiacture.

Further objects will appear from the'detail description taken in connection with the accompanying drawing, in which:

Figure l is a perspective view of a binder embodying this invention;

'Figure- 2 is a section, somewhat enlarged, on the line 2 2, Figure 1; c

Figure 3 is a still further enlarged section on the line 3-3, Figure 2; a

Figure 4 is an enlarged detail on the line 4-4, Figure 2; and

Figure 5 is a detail showingthe post and retaining head therefor.

Referrin -to the accompanying drawing,

the binder, as shown, comprises a back 1 having sides 2 of paper, board or any other suitable material and provided with a covering 3 which may be'o f fabric, leather or any other suitable material, this covering also forming the hinge connections 5 One of the sides 2 is provided with a pair of base strips 5 and 6 of metal or any other suitable material, each of which is pressed or sunk into the back and secured at one end by a rivet 7, while the other endsare turned under as shown at 8. The strip 5 is formed at one end as shown at 9 to pro-, vide with the strip 6 apintle socket, as shown in Figures 2 and d. Near the other ends the strips are perforated as shown at 10, while the side 2 is recessed as shown at 11 toprovide a rimmed retaining socket as shown in Figures 2 and 3.

An arch 12 has one of its legs bent laterally as shown at 13 to form a pintle arranged to take into the pintle socket as shown in Figure i, the back and the strips being recessed as shown at 14 and 15 to perunit entrance of the pintle into its socket, and

ti e objects of this-invention is to T r1 loose leaf binder arranged to hold No. 563,281. Renewed April 14, 1927.

to permit the arch,toswing about its pintle with its otherleg towards and from the retaining socket; Thetip of this other leg 1S notched as shown at 16 .so as to takeover the rim formed by the strips 5 and (5 overhanging the retaining socket. v

The arch is arranged to be detachably connected with the binder back by slipping its pintle into itsvsocket and this arch is preferably of a springy metal, such as steel. When, the archpintle engagesits socket, the tip thereof, when moved downtowards the retaining socket, will be normallyin the position shown in. dotted lines in Figure 3, so as to be beyond the confines of, this retaining socket. By, however, twisting the arch and springing-its tip to the right and down wardly, Figure 3, this tip can be sprung into its socket sov as to snap thereinto with its notch engaging the rim formed by the strips and 6. Thetipicanbe rounded as shown in Figure 3 so as to readily permit such engagement, and in this position the arch will be firmly retained as shown in Figures 1 and 2. It will, of course, be understood that the arch tip can be disengaged from its socket by reverse movement and that the arch may then be entirely removed from the back by slipping the pintle out of the socket. r

The arches connected as shown provide means for securely holding the loose leaves 17' in position, however, permitting these leaves to be turned over on the other side as 1s required in some cases moreover, the leaves can be entlrelyremoved and replaced and the binder can be built up to the desired extent. In some cases, it is not necessary for the sheets to be turned over. In

such a case, it is only necessary to provide posts with some retaining means. Such a post is shown in Figures 1, and 2 and 5. It comprises an internally threaded tube 18 having a shoulder 19 formed on or attached to the post and bearing on-the strip 6, the shank of the post passing through the strips and the back 2 and being riveted over as shown at 20. This post is adapted to receive the threaded shank 21 of a knurled head 22. A post is placed intermediate the sockets and strips 5 and 6, thus placing it between the legs of the'arch; accordingly, the post does .not interfere with the free manipulation of the sheets 17 when the arches are in osition' b however removin the arches as previously described, the sheets can be placed on the posts and secured by the retaining heads 22.

It will, therefore, be seen that the inven tion accomplishes its objects. A binder is provided which is not only simple in construction but effective in its action and cheap to manufacture. Firm sustaining means are )rovided for holding the arches as well as the posts in position and the binder can be readily converted to one form or the other. All metal parts are covered and substantially flush with the back, so as to present a neat and pleasing appearance.

It is obvious that various changes may be made in details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.

Having thus described the invention, what is claimed is:

1. A loose leaf binder comprising a back provided with superimposed strips, one of which has a part thereof depressed below the other to form a pintle socket, and an arch having a pintle adapted for engagement with said socket and having a tip adapted to interlock with said strips.

2. A loose leaf binder comprising a back provided with a base strip, a detachable leafholding arch thereon and a filing post on said base adapted to hold leaves upon removal of the arch.

3. A loose leaf binder comprising a base, a detachable leaf-holding arch thereon, and

a filing post on said base intermediate the legs of said arch, adapted to hold leaves upon removal of the arch.

4. A loose leaf binder comprising a base, a leaf-holding arch detachably mounted thereon, and a post on said base intermediate the attachments of the legs of said arch, a cap screw threaded into the post, said post being adapted to hold leaves upon detachment of the arch.

5. A loose leaf binder comprising a'base provided with a pair of spaced sockets, a detachable leaf-holding arch adapted to engage with said sockets, and a filing post on said base intermediate said sockets, arranged to hold leaves upon removal of said arch.

6. A loose leaf binder comprising a base, a leaf holding arch, and a filing post mounted thereon, said arch being detachable from the base to permit independent use of the post for filing, said post being spaced from said arch so as to permit movement of the leaves on said arch.

7. A loose leaf binder comprising a base, an arch mounted thereon, a filing post mounted thereon intermediate the legs of said arch, the top of said post being below the bend of said arch, said arch being completely detachable to permit independent use of the post for filing.

In testimony whereof I afiix my signature this 6th day of May, 1922.
